Solution: A mixture in which one substance is dissolved in another Vein: A narrow slab of mineral that is sharply different from the surrounding rock.

At 'Crater of Diamonds' State Park in Arkansas diamonds can be found.
Millions of years ago great pressure and heat changed carbon atoms into the hardest known substance called diamond.
Which are deep formed in the mantle erupted carrying diamonds to the surface.
Processes that form minerals:
Minerals can form in two different ways, through crystallization of melted materials and through crystallization of materials dissolved in water.
Crystallization is the process by which atoms are arranged to form a material with a crystal structure.
Minerals from Magma:
Minerals from as hot magma cools inside the crust or as lava hardens on the surface.
When these liquids cool to a solid state, they form crystals.
Minerals from hot water solutions:
A solution is a mixture in which one substance dissolves another.
As hot water solutions cools the elements and compounds leave the solution and crystallize as minerals.
Minerals formed by evaporation:
Just like salt crystals can be seen after letting salt water evaporate, thick deposits of the mineral halite is formed over millions of years when ancient seas slowly evaporated.
In the United States such halite deposits occur in the Mid west, the South west and along the Gulf coast.
Where minerals are found:
Earth's crust is mostly made up of common rock - forming minerals combined in various types of rock.
Less common and rare minerals ,however ,are not distributed evenly throughout the crust.
Instead ,there are several process that concentrate minerals, or bring them together in deposit.
